(a), pelvic mirror
In 1901, Russian gynaecologist D.O.ott also cut the vagina under the forehead illumination and placed it in the cystoscope to observe the abdominal cavity of a woman. This is the first pelvic mirror.
(B), diagnostic laparoscopy In 1910 Jacoboeus.H.C for the first time the use of a cannula needle inserted into the abdominal wall and through the cannula into the air into the abdominal cavity, and then placed into the cystoscope for examination. In 1944, Raoul Palmerjiang of France officially applied laparoscopic surgery to the field of gynecology. He examined a large number of infertile patients and developed a routine for laparoscopy. In 1963, a monograph was published, systematically introducing some simple operations under laparoscopy, such as: tubal ventilation, fluidization; simple organ adhesion separation; tubal electrocoagulation; endometrial ectopic focus electrocoagulation , electrocautery, etc.
(III) Surgical Laparoscopy After entering the 1970s, due to the invention of cold light source and glass fiber endoscope, the artificial pneumoperitoneum monitoring device of Semm of Germany---automatic pneumoperitone machine came out, and the laparoscopic surgery has developed vigorously. Because it is small in injury and does not require laparotomy, it is quickly accepted by both doctors and patients. In 1980, Dr. Nezhat in the United States began surgery with a TV laparoscope. The surgical field is clearly displayed on the screen, which expands the field of vision. Many doctors can see the operation process at the same time, which is conducive to technical communication and discussion, and also facilitates the cooperation of assistants and the assistance of an anesthesiologist. In the late 1980s, Professor Kurt Semm of Germany invented and created many new surgical instruments and techniques. Such as: microscopic suture instruments, irrigation pumps, various pliers, scissors, combination pulverizers, cutters, etc. There are many ways to stop bleeding under the microscope: advances in techniques such as monopolar coagulation, bipolar coagulation, ligation ferrules, internal suture techniques, titanium clips, and staplers have enabled more complex procedures to be performed under the microscope. In 1988, Reich H performed the first laparoscopic hysterectomy. After that, the scope of gynecological surgery became larger and larger, and almost 90% of gynecological operations were performed under laparoscopy.
